A stepper motor or a step motor is a brushless, synchronous motor which divides a full rotation into a number of steps. Unlike a brushless DC motor which rotates continuously when a fixed DC voltage is applied to it, a step motor rotates in discrete step angles.The stepper motor can be controlled with or without feedback. Stepper motors work on the principle of

Understanding the Dual Y Axis in Charts. When the data values in a chart vary widely from data series to data series, or when you have mixed types of data (for example, currency and percentages), you can plot one or more data series on a secondary vertical (Y) axis. The scale of the secondary Y-axis reflects the values for the associated data

The gearbox is a vital component of wind turbines; it resides in the nacelle. A gearbox increases the main shaft speed from around 12–25 rpm* (for most of today's turbines) to a speed suitable for its generator. For this reason, the shaft on the generator side is called "high-speed shaft.". Because a turbine must follow the wind and

Accelerometers are electromechanical devices that sense either static or dynamic forces of acceleration. Static forces include gravity, while dynamic forces can include vibrations and movement. Accelerometers can measure acceleration on one, two, or three axes. 3-axis units are becoming more common as the cost of development for them decreases.

Aug 24, 2021Summary. A motor is a mechanism that transforms the motor's energy into mechanical energy. Its operation is based on the electromagnetic interaction of the magnetic field created by the structure's coil and magnet. It is classified into two categories based on the direction of the magnetic field: axial flux motors and radial flux motors.
